Patent JP-H01270104-A (JP)
Title: Automatic controller
Inventor: ONO KAZUTERU
IPC: G05B11/42
Filed: 1988-04-22
Abstract: PURPOSE:To reduce time delay in the switching of control by constituting a device in such a way that the output of a final stage is fed back to each of control circuits having integrators, respectively, and providing a limiter so that the output of the integrator can be set at a value within +alpha and -alphaof the output of the final stage. CONSTITUTION:Firstly, in case of performing the pressure control operation of the pressure of a pipeline 3 by lowering pressure setting 71P from a state where a CV2 is controlled by the output of an LVG 75N, a proportional integrator 74P' intends to perform integration to a lower side since the output of the pressure setting 71P is higher than pressure P. However, since the output of 76 is fed back to the 74P', the output of the 74P' is reduced to a level not exceeding the output -alpha of the 76. When the output of the pressure setting 71P is reduced slightly less than the pressure P of the pipeline 3, the output of the 74P' is integrated to an upper side, and is switched by integrating only by -alpha. Also, even when the pressure setting 71P is increased, the output of the 74P' is integrated to the lower side, and is switched by integrating by +alpha. In such a way, it is possible to minimize the time delay and the fluctuation of the pressure.

Filed: 1981-06-25
Abstract: PURPOSE:To obtain large pitches of printed patterns by using a small-diameter printing plate by a method in which plural cylindrical printing plates having different diameters are used an unit pattern of a length corresponding to the least common multiple of the peripheral length of each printing plate is formed. CONSTITUTION:For example, printing is made on the same printing mediums by using two cylindrical printing plates 1 and 4 having a 3:5 diameter ratio to form an unit pattern of a length C coresponding to the least common multiple of the peripheral length of each of the printing plates 1 and 4. By this, a printing with the unit pattern of the length C can be obtained by using the cylindrical printing plate having smaller peripheral length, thus eliminating the need to use large-diameter cylindrical printing plates. Therefore, the cost of manufacturing printing plates can be reduced and also the delivery work and the mounting and demounting works of printing plates for machine can be made easier.

Abstract: PURPOSE: To enable a focused light beam to be used as a heat source by heating the prescribed region of an amorphous solid provided with a first refractive index and converting it into a second refractive index. CONSTITUTION: This optical storage device 40 is provided with a motor 52 and designed to move a disk 48 having a write laser 44, a read laser 46 and a storage medium 50. In addition, the laser 44 is provided with a function for supplying a laser beam 58 to the upper face 60 of the disk 48 through a lens 59. Then, an amorphous solid is selected that has a first refractive index, the lens 59 supplying a laser beam 61 focused on the surface 60 of the disk 48. As a result, with the prescribed region of the amorphous solid heated by the beam 61, the refractive index is converted to a second refractive index. Consequently, using a material with a sufficiently high crystallizing temperature or a melting point, the amorphous can be converted without overwriting through the crystallization of the material. Incidentally, reading is possible repeatedly by writing this information on a carbon film.
